ROAD-WORKING MACHINE.

Specification of Letters Patent.

Patented April 3, 1906.

Application filed July 17, 1905- Serial No. 270.031.

To aZZ, whom 11-1; 12mg concern.-

Be it known that we, WILLIAM J. MCBRIDE and JOHN J. ALFORD; citizens ofthe United States, residing at Fort Worth, in the county of Tarrant andState of Texas, have invented a new and useful Road-Working Machine, ofwhich the following is a specification.

This invention relates to road working machines, and it has particularreference to that class of road-working machines which are designed esecially to operate upon banks at the sides 0 the road for the purpose oftrimming such banks and moving the surplus dirt in the direction of thecenter of the road.

The object of the present invention is to simplify and improve theconstruction and operation of this class of machines and with these andother ends in view, which will readily appear as the natureof theinvention is better understood, the same consists in the improvedconstruction and novel arrangement and combination of parts, which willbe hereinafter fully described, and particularly pointed out in theclaims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that various changes, alterations, and modifications may be madewithin the scope of the invention and without departing from the spiritor sacrificing the e'lhciency of the same.

In said drawings, Figure 1 is a side elevation of a road-working machineconstructed in accordance with the principles of the invention, parts ofthe same being shown in section. Fig. 2 is a top plan view, partly insection, of the said machine.

Corresponding parts in both figures are indicated throughout by similarcharacters of reference.

In this improved machine two beams or side members are employed--viz.,the main beam 1 and an auxiliary beam 2said beams converging forwardlyand abutting upon each other, the abutting portions being connected by abolt 3, carrying a draft member, such as a clevis 4. Near the front endsof the beams there is introduced between them a spacing memberconsisting of a trapezoidal block 5, which normally rests upon flanges 6upon the inner sides of the beam. The block 5 is shown as provided withtrunnions 7, extending through apertures 8 in the respective beams, withwhich said block is also connected by means ofa transverse bolt 9. Arung 10 is introduced between the beams about midway of their lengths,and each of said beams is provided near its rear end with alaterally-extending bracket, said brackets being. designated,respectively, 11 and 12. These brackets are provided at their outer endswith dowels, as 13, engaging the beams upon which they are secured bymeans of fastening members, such as clips 14. The inner meeting ends ofthe brackets 11 12 are jointed together and connected detachably, as bymeans of a bolt 15.

The main beam carries a standard 16, and it is provided with handles 17,connected with and spaced from said standard by means of a rung 18.

19 is a colter or cutter having an upright member20, which is connectedwith the outer side of the beam bymeans of a clip 21. The heel 22 of thecolter is connected with the beam by means of a brace 23, and it is alsobolted or otherwise secured, as indicated at 24, to the outer side ofthe standard 16. The latter is connected with the beam by means of aninclined brace 25, and the lower end of said standard carries a scraperwhich is in the nature of a plow member 26, which is disposed to throwdirt in an outward directionthat is to say, in the direction of theauxiliary beam, which is distant from the bank operated upon, so thatthe dirt will be thrown by said scraper in the direction of the middleof the road.

The spacing-block 5 is provided with a tubular member or sleeve 27,through which extends a shank 28, carrying a caster-wheel 29, said shankbeing supported for rotation in'the sleeve by suitable means, such as acollar 30, having a set-screw 31, whereby it may be adjusted. Asupporting-wheel 32 is also suitably mounted near the rear end of theauxiliary beam 2. The bracket member 11 has a slot 33, through whichextends a shank 34, carrying a wheel 35, which travels in rear of thescraper 26. A lever 35 is pivoted upon the rung 10, and said lever has aslot 36, in which the upper end of the shank 34 is loosely secured, asby means of a pin 37, engaging a transverse slot 38. This constructionwill provide lost motion to enable of which has a handle 39, adapted toengage any one of a plurality of notches 40 in an upright 41, securedupon the rear side of the bracket member 11 for the purpose of securingthe Wheel-carrying shank in any position to which it may be adjusted.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.Then the device is in position for operation, the colter member may beguided very close to a bank at the side of a road, thus enabling saidbank to be trimmed, as will be readily understood', the surplus dirtbeing moved in the direction of the center of the road by the scraper26. The disposition of the various parts is such that the colter orcutting member may be held in very close engagement with the bankwithout interfering with the free action of the team, while by thearrangement of the auxiliary beam and the brackets and connectingmembers the draft will be equalized, so that the machine may travel in astraightforward direction without hindrance. The supporting-wheel 35 maybe raised or lowered, thereby depressing or elevating the colter orcutting member, as well as the scraper, and thus enabling adjustment tobe made according to the condition, encountered when the machine is inoperation. When the machine is to be transported from one place toanother, it may be taken apart by simply detaching the bolts 3, 9, and15, thus permitting the beams and related parts to be convenientlyloaded into a wagon.

It will be particularly observed that the beam 2, which constitutes aportion of the frame of the device, is not a tool-carrying beam, but issimply a guiding or balancing member, whereby the main tool-carryingbeam and its related parts are properly sustained in positon foroperation and which also facilitates the attachment of the draft at thedesired point. By the construction and arrangement of parts herein shownand described the machine may be guided very close to a bank at the roadside, so as to trim the bank and move the dirt thus loosened in thedirection of the center of the road, which is thus improved for traffic.The cutting and scraping tools or members are under no circumstancesconnected with or supported by the auxiliary or guiding beam 2.

Having thus described the invention, what is claimed is 1. In aroad-working machine, a main beam having a standard, a cutting memberconnected with said beam and standard and supported thereby in avertical plane, and a scraper supported by the standard to move the dirtloosened by the cutter in an outward direction, in combination with anauxiliary supporting-beam connected with the main beam at its front end,spaced therefromat its rear end, and provided with rotary supportingmeans.

2. In a road-working machine, a beam having a laterally-extendingbracket, a wheelcarrying member extending through a slot in said bracketwhereby said wheel is spaced laterally from the beam, an adjusting-leverconnected with the wheel-carrying member for adjustment of the latter, astandard connected with the beam, a cutting member supported by the beamand the standard, a scraper carried by the latter, and an auxiliary beamconnected with the front end of the main beam and provided at its rearend with a bracket connected with the bracket extending laterally fromthe main beam and rotary supporting means for the auxiliary beam.

3. A main beam and an auxiliary beam secured together at their frontends, spacing and connecting means including a rung interposed betweensaid beams about midway of their lengths and brackets near the rear endsof said beams, a wheel-carrying shank extending throughone of saidbrackets, an operating-lever pivoted upon the rung and having looseconnection with the wheel-carrying shank, means for securing said leverat various adjustments, and rotary supporting means connected with theauxiliary beam and with a spacing member near the front ends of thebeams.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
